These Smart Bullets Can Steer Themselves

The U.S. military has bombs that are self-guided to hit targets with supreme accuracy-and next up will be bullets with similar capabilities. The research agency of the Pentagon, the Defense Advanced Research Projects Agency or DARPA, is developing smart bullets that can change direction mid-air. The code name to this project is EXACTO: Extreme Accuracy Tasked Ordinance. So how do they work? The tip of the bullet has optical sensors that send signals to tiny fins on the bullet to help steer the bullet toward the target. The phrase "dodging a bullet" may soon become a thing of the past.
